Yes, Romney was crushing Obama in a back and forth exchange about taxes on small businesses and Obama desperately turned to the moderator and asked, "can we talk about something else?"

If I recall the exchange started with Obama saying he only wants to raise taxes on 3% of small businesses and that 97% would not see their taxes raised. Romney countered that the 3% represent half the small business jobs and thus 1/4 of all jobs with a study concluding that the proposed tax would cost 700,000 jobs. Romney pointed out that any tax revenue generated from the businesses would be more than countered by the revenue lost from losing that many tax paying employees.
